P0998Shift Solenoid F Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Low-voltage fault, typically a short to ground, in the control circuit of shift solenoid F. Two makers document it. Nissan lists P0998 as shift solenoid F in bulletin NTB15-037 for the 2012–2017 Versa, Versa Note and Sentra with the RE0F11A CVT, whose two-speed auxiliary gearbox uses a low brake, a high clutch and a reverse brake; if the shop manual check points to the transaxle, the bulletin has only the control valve replaced. Mitsubishi's 2019 service manual for a six-speed automatic names P0998/P0999 the low clutch shift solenoid valve system and counts it among faults that can cause gear ratio errors. CARB requires transmission outputs to be checked for circuit faults. P0999 is high, P097F open.
